Definitions
- the present invention relates to foams having deodorant and anti-organism properties such as anti-bacterial and mildew resistance properties. These foams are usable for multi-purposes.
- the present invention also relates to a water-nonpermeable deodorant, anti-bacterial sheet, which is obtained by laminating the foams with a fiber sheet.
- the sheet maintains deodorant and anti-bacterial properties even after having been washed. It can be used for various purposes.
- Deodorant particles are partially exposed to the atmosphere at the surface of the above mentioned film, but primarily the particles are enclosed in the film and therefore the particles would absorb odorous gases such as ammonia through the thin polypropylene layers which are positioned between the particles and the surface of the film.
- Thick plastic moldings having deodorant properties are not known.
- the thickness ranges in general from 10 to 100 microns.
- the thickness of foam shells lie in the range of several microns and is thinner than that of the above mentioned films.
- plastic compositions with the deodorant property could be obtained and the deodorant property of such compositions might be superior to that of the films, if deodorant particles could be contained in high expansion ratio from plastics by a suitable method.
- the plastic compositions resulting therefrom would exhibit both the above mentioned deodorant and anti-organism properties.
- the materials to be added in plastics should not have an adverse effect on the inherent performance of the plastics such as strength and color and also should not have an adverse effect on the foaming property.
- the particles comprising ferric compound and ascorbic acid, described in the above mentioned Japanese Patent Provisional Publication No. 61(1986)-60732, have an adverse effect on the foaming property and, when a cationic, organism activity preventing agent is used, the effect of such an agent is reduced.
- Deodorant, anti-bacterial woven fabrics and non-woven fabrics to which deodorant agents and anti-bacterial agents are applied by conventional methods, such as dipping, sandwiching, coating and the like are well known, but such woven fabric or non-woven fabric which retains deodorant and anti-bacterial properties after washing have been not known.
- the present inventors successfully obtained the foamed plastics of the present invention by using the combination of a deodorant agent and organism acitivity preventing agent, both of which are insoluble or difficulty soluble in water.
- the present inventors in proceeding with the research found that a foam, prepared by mixing a selected deodorant agent and anti-bacterial agent under selected conditions in an expandable urethane material which forms closed cells, followed by foaming the mixture exhibits deodorant and anti-bacterial properties.

- the present invention relates to deodorant, anti-bacterial foamed plastics which contain deodorant and anti-bacterial particles.
- a foamed polymer composition according to the present invention comprises a foamed polymer, fine particles of a deodorant and fine particles of an antibacterial agent.
- the composition preferably comprises 100 parts by weight of the foamed polymer, 3 to 30 parts by weight of the deodorant and 0.2 to 2 parts by weight of the antibacterial agent. It is preferable that the fine particles of the deodorant and those of the antibacterial agent have a particle which is sufficiently small in size, such that it would at least pass through a sieve having 30 mesh according to JIS. The fine particles preferably have an average size of 30 to 500 mesh, more preferably 200 to 300 mesh.
- the composition may be in the form of a film.
- the present invention also provides a sheet laminate which comprises a fiber sheet and a sheet of the foamed polymer composition as defined above, which is laminated on the fiber sheet.
- reaction type deodorant agents especially inorganic deodorant agents
- Deodorant agent and anti-bacterial agent are preferably insoluble or difficulty soluble in water.
- Basic zinc carbonate and ferrous sulfate monohydrate are examples of the deodorant agent and N(fluorodichloromethylthio)phthalimide and N,N-dimethyl-N'-phenyl-N'-(fluorodichloromethylthio)sulfamide are examples of the anti-bacterial agent, which are effectively used.
- Both the deodorant agent and anti-bacterial agent are essentially in the form of fine particles. The particles preferably will at least pass through a 30 mesh screen.
- Such deodorant and anti-bacterial agents are added to an expandable plastic material, along with the required compound materials, such as a foaming agent and a filler to form the composition which is foamed under the usual conditions to obtain the foamed plastics.
- the polymer to be used in the present invention includes polyurethane, polyethylene, polypropylene and polystyrene.
- 3 to 30 g of a deodorant agent and 0.2 to 2 g of an anti-bacterial agent are preferably added to 100 g of a plastic resin solid. If the quantities are less than any one of these values, the remarkable effects of the foamed composition of the present invention are not obtained. On the other hand if the quantities are more than any one of these values, the expandability of the plastic would tend to deteriorate.
- the expansion ratio is usually not affected by addition of the agents within the above mentioned range, but tends to decrease with addition of the Therefore, it is recommended that production be carried out after a small scale test.
- Foams of the present invention regardless of whether they are closed cell foam or open cell foam, are excellent for the removal of odors in the atmosphere and the effect of the anti-bacterial property and the mildew resistance, continues for a long period of time.
- the present invention relates to a deodorant anti-bacterial sheet comprising a laminated fiber sheet and foamed sheet containing the deodorant particles and anti-bacterial particles which maintains deodorant and anti-bacterial properties even after washing.
- a deodorant anti-bacterial sheet comprising a laminated fiber sheet and foamed sheet containing the deodorant particles and anti-bacterial particles which maintains deodorant and anti-bacterial properties even after washing.
- 3 to 30 g/m 2 based on the sheet product of a deodorant agent and 0.2 to 2 g/m 2 based on the sheet product of an anti-bacterial agent are suitably used.
- deodorant particles and anti-bacterial particles may be mixed in a raw material composition containing a foaming agent and may be foamed by a conventional method.
- the above mentioned additives affect on the expansion ratio depends on the situation. Therefore, it is desirable that after the preliminary experiment has been conducted, the production thereof is carried out. But usually expansion ratio is hardly affected within the above mentioned addition ranges of additives.
- Foaming may be conveniently carried out by dry foaming.
- a foam sheet may be obtained by foaming in a sheet form or by slicing a bulk foam. Any fiber sheet such as woven fabrics, non-woven fabrics and knit fabrics may be used.
- Foam plastics of the present invention having deodorant and anti-bacterial effects, are useful for making other articles deodorant and anti-bacterial.
- the foamed plastic of the present invention is useful, for making an elastic foam such as a polyurethane foam, with high expansion ratio.
- the sheet material of the present invention is unexpectedly improved in heat-retaining property and cushion property, and can be subjected suitably to various processes such as cutting, adhesion, and sewing.
